The gears-1294- are adapted to be ro-V tated'inv unison by suitable gears -l31- mounted upon a shaft-lQ--journaled in brackets -133 carried by castings -130-. The shaft -132- has operably mounted upon it a gear -134- adapted to mesh with a relatively .small gear -135 mounted upon the end of a shaft 13G- journaled in a bracket --137- mounted upon one of the posts 12B- and in a bearing -138- mounted upon a brace -139- extending upwardly and inwardly from a base -140- to engageone of the posts -123- at a point adjacent the cap -88- of the vapor condensing apparatus -89-. The corresponding one of the posts 423- upon the opposite side of the centrifugalevaporating 'apparatus is provided with a similar brace 139- rising -from av similar base l40 and' in like manner extending upwardly the post at a point adjacent the cap -88- of the Vapor condenser These braces areconnected at their base by a suitable transverse bar 141 The shaft -136- is 'provided `with a suitable-handle --142- for rotating the same, thereby in turn rotating the shaft #132-, the gears. -131- and thereby the coacting gears -129- for simultaneously raising or lowering, as desired, the blocks 121- to Araise and lower that portion of the apparatus, which may be termed the centrifugal evaporating portion, into engagement or pressing coaction with the cap '-88- of the vapor condenser 89--.

A suitable framework is provided for supporting the chamber -101- of the vapor condensing'- apparatus, one side of which framework is shown in Fig. 3, the framework upon the opposite side being identical therewith, and comprises a suitable vertical post -143-carrying, in connection with 'post -123-, longitudinal bars 1114-1 supported upon a similar structure.

Then the centrifugal evaporating apparatus is moved downwardly to such 'an extent that the casting -.8G- and ring -85- of the apparatus are disengaged with` the cap -88- and the shaft -64- of the beater is withdrawn from 'the hearing and inwardly to `engage from that shown inv a --Fig. 3 -is provided with similar brackets *66*, suitable mechanism is provided for tiltingthe centrifugal evaporating apparatus upon its trunnions *120* to permit removal of the beater from the chamber *35*. This mechanism comprises` as best shown in Figs. 3 and 4. suitable bars *146'* each havine one end connected to ends to suitable beveled gears *149* meshing with other suitable beveled gears *150* `mounted upon a shat't *151* carried bv the brackets *14H* and upon which shaft a suitable sprocket *152* is mounted, operably7 connected by chain or otherwise to a second sprocket *153* mounted upon a shaft *ll* journaled in a bearing` operably carried by a post *123*. The sprocket *153* is adapted to be rotated by a suitable handle *156* for transferring rotary movement to the sprocket *152*, the gears *149* and *150* for turning the shafts *l-li'* thereby longitudinally moving the bars *146* as desired, either to tilt the apparatus from vertical position' or to return the same to vertical position after tilting.

The mechanism described constitutes means for raising the heater orcontainer portion of the apparatus toward-and from the stationary cap 8H forming an elbow connection between the liquid evaporating chamberand the vapor condensing apparatus. In addition the mechanism constitutes a means for tilting or moving the liquid evaporating chamber about its supporting`pivots to permit removal of the interior parts for cleaning of the same. Modifica tions may be made in the details of construction without departing from the invention as set forth in the appended claims.

What I claim isz* 1. In an evaporat-ing apparatus` a framework. a liquid e'vaporating chamber anda cap theret'orboth carried b v said framework. one otsaid elements being movable on the framework toward and from the other, a rotary beater vwithin the liquid evaporating chamber and a sectional shaft for driving said beater, said shaft separable into said sections when the movable element is moved away from the coperating element.

2. In an evaporating apparatus, a framework, a liquid evaporating chamber and a cap therefor, both carried by said framework. one of said elements being movable on the framework toward and from the other, a rotary beater within the liquid evaporating chamber and a sectional shaft for driving said beater, said shaft separable into said sections when the movable element is moved a 'ay from the coperating element, and interlocking parts on said seetions engaged to effectrotation of the sections when the movable element is brought into cont-act with the co-actingl element.

In witness whereof I have hereunto set my hand this 27th day of November, 1916.
